PROCESS FOR CONTROLLING THE POLISHING PROCESS OF AN OPTICAL ELEMENT

摘要

The invention concerns a process for measuring and/or controlling a polishing process of an ophthalmic element (1) comprising the steps of manufacturing at least two cavities (2, 3) on the surface of the element to be polished, the depth of the first cavity (2) being smaller than the depth of the second cavity (3) operating the polishing process considering the element (1), in order to check that the first cavity (2) is suppressed and that the second cavity (3) is present.
